Man, who even made this in the first place? I can find a refrance to it here (Google Web Cache since forums are down) but still. It's uncanny how it resembles one of those early 90s GIFs, down to the bad jagged transparency outline around the head (but this time, the style fits it so well... in scaring the living shit out of us).

This is actually my spray in TF2!
And in-game it slows down which, believe it or not, makes it creepier.
But I've grown attached to seeing his face on random walls; and seeing people desperately try to cover it up.
